I used this antenna with a Sierra Wireless 250U USB modem connecting to a Spring 3G tower. Without this antenna my signal was about -78dbm. I initially used the antenna indoors through a window with direct line of sight to the tower. That produced a signal of about -71dbm. Surprisingly, when I just opened the window the signal strength went up to -60dbm. My windows are "low-E" glass with a coating in case that matters. Just mentioning it in case others try something similar. I ended up mounting this outside aimed directly at a tower about 2 miles away and the signal strength ranges from -58dbm to -61dbm throughout the day.
